> anyone receiving threats online should report it to law enforcement

The fact that you suggest this is proof that you've never had to do so. This is literally part of what I do for a living. I work with people going to law enforcement, sometimes as an advocate. Your local police have no idea what their laws are regarding online stalking/harassment, nor do they have interest in prosecuting it without a significant amount of external prodding, usually from reporters. You're welcome to look up anything I've written on the subject about this for reference.
